Pre-Crisis Roger C. Corbin, who took up the mantel (if not his fashion sense) of his brother, the first Metallo, after John Corbin's apparent death.
Visually, this 'action figure' is a force to behold. He even has a cool action feature similar to that of the Battle Armor He-Man and Skeletor of the eighties...
Finally, his body is hollow lightweight plastic akin to a Happy meal toy and just feels cheap. I've considered taking him apart and flipping the arm around so it rests on his hip but I'm worried if I take him apart (he's simply held together by a handful of screws!) his Kryptonite heart will go 'sproing!', therefore I have yet to do so. I imagine when apart I could also fill his hollow legs with some clay or something to weigh him down so he doesn't feel so light and top-heavy, but again the effort just doesn't seem worth it at the moment.
He's visually wonderful, yes, and as a statue of cheap plastic he fits the bill, but that arm really detracts from him being a mere display piece.
If you are an artist, maybe you can use him as a brush holder or something at your art station.
